Description

Technical Field

[0001] This utility model relates to a tunnel ventilation system and belongs to the field of tunnel construction technology. Background Technology

[0002] Tunnel ventilation is one of the key technologies in tunnel construction, especially for long tunnels constructed using the drill-and-blast method. The ventilation effect directly determines the tunnel construction progress and directly affects production costs. Currently, tunnel ventilation mainly uses single-head forced ventilation, in addition to other technologies such as tunnel ventilation, exhaust ventilation, and compartmentalized ventilation.

[0003] Patent CN220667620U discloses a tunnel ventilation system comprising a flow guiding mechanism, a fire detection mechanism, and a protective mechanism. The flow guiding mechanism includes a jet fan positioned near the tunnel ceiling. The fire detection mechanism is electrically connected to the jet fan and detects fires within the tunnel. The protective mechanism is mounted on the jet fan and is used to cool it. The fire detection mechanism is also electrically connected to the protective mechanism. This application effectively mitigates the problem of fire-affected fan operation.

[0004] While the solutions in the aforementioned patents can reduce the impact of fire-induced temperature rise on the operation of the jet fan, the tunnel ventilation system in these patents does not facilitate the purification of the air inside the tunnel. Construction inside the tunnel will result in the air containing a large amount of dust, which will be carried into the ventilation ducts. After prolonged use, the accumulation of dust inside the ducts will affect the ventilation effect inside the tunnel.

[0005] Therefore, a tunnel ventilation system is proposed here. Utility Model Content

The snap-fit ​​assembly includes two support blocks fixed on the upper and lower sides of the connecting plate, a push rod slidably sleeved inside the support block, a transmission plate fixed at one end of the push rod, and positioning plates fixed at both ends of the transmission plate away from the push rod.

[0008] Furthermore, an anti-slip pad is fixed to the end of the push rod away from the transmission plate, and a compression spring sleeved around the push rod is fixed between the anti-slip pad and the support block.

[0009] Furthermore, the connecting plate has a set of first positioning grooves inside, and the filter plate has a set of second positioning grooves corresponding to the positions of the first positioning grooves inside, and the positioning plate can be sequentially embedded into the interior of the first positioning groove and the second positioning groove.

[0010] Two support frames are fixed on one side of the connecting plate, and the filter plate can slide between the two support frames. A cleaning component for cleaning the surface of the filter plate is provided on one side of the support frame. The cleaning component includes a positioning block fixed on one side of the support frame, a sliding rod fixed inside the positioning block, a moving plate slidably sleeved around the sliding rod, and a cleaning brush fixed on the side of the moving plate near the connecting plate.

[0011] Furthermore, each of the support frames has a connecting groove on one side, and the cleaning brush can move into the interior of the connecting groove.

[0012] Furthermore, a lever is fixed to the side of the movable plate away from the cleaning brush, and the lever is located in the middle section of the movable plate.

The snap-fit ​​assembly 6 includes two support blocks 61 fixed on the upper and lower sides of the connecting plate 3 respectively, a push rod 62 slidably sleeved inside the support block 61, a transmission plate 63 fixed at one end of the push rod 62, and positioning plates 64 fixed at both ends of the transmission plate 63 away from the push rod 62.

[0031] Please refer to this carefully. Figure 3 An anti-slip pad 65 is fixed to one end of the push rod 62 away from the transmission plate 63, and a compression spring 66 is fixed between the anti-slip pad 65 and the support block 61 and sleeved around the push rod 62.

[0032] The connecting plate 3 has a set of first positioning grooves 31 inside, and the filter plate 4 has a set of second positioning grooves 41 corresponding to the positions of the first positioning grooves 31 inside, and the positioning plate 64 can be embedded into the interior of the first positioning grooves 31 and the second positioning grooves 41 in sequence.

[0033] In the above scheme, the compression spring 66 pushes the anti-slip pad 65 to move the push rod 62, and the transmission plate 63 drives the positioning plate 64 to be embedded in the second positioning groove 41, which can fix the position of the filter plate 4.

[0034] Please refer to this carefully. Figure 4 Two support frames 5 are fixed on one side of the connecting plate 3, and the filter plate 4 can slide between the two support frames 5. A cleaning component 7 for cleaning the surface of the filter plate 4 is provided on one side of the support frame 5. The cleaning component 7 includes a positioning block 71 fixed on one side of the support frame 5. A slide rod 72 is fixed inside the positioning block 71. A moving plate 73 is slidably sleeved on the periphery of the slide rod 72. A cleaning brush 74 is fixed on the side of the moving plate 73 near the connecting plate 3.
